TECHNIQUES FOR COMPARING ALTERNATIVE EDUCATION INVESTMENTS EDUARDO VELEZ AFTH1 December 1998
THREE MESSAGES I. ECONOMIC ANALYSIS IS IMPORTANT IN EDUCATION II. ECONOMIC ANALYSIS IS POSSIBLE IN EDUCATION III. EXPAND EXPECTATIONS SLOWLY, CAREFULLY
I. ECONOMIC ANALYSIS IS IMPORTANT IN EDUCATION • Economic analysis is a tool to analyze best investments from an economic point of view • Necessary (convenient) for sector analysis and for project design • Provides a set of information. Education indicators are another set. • It helps answer the following questions: A. In which education sub-sector should one invest? B. What kind of investment in each sub-sector? C. Are the planned investments sustainable? D. What are the equity implications?
A. In which education sub-sector should one invest? • The first decision concerns the educational level where it makes most sense to invest. Intra-sectoral but also inter-sectoral allocations • This decision should usually be made prior to project identification, when the overall country assistance strategy is defined and specific priorities are set for the education sector within that context. • Instruments: • CAS (coverage, quality, efficiency, sequence of investment) • Public expenditure review
B. What kind of investment in each sub-sector? • There are different ways of achieving educational goals (identification of education inputs) • Choosing among various alternatives implies the ability to measure the costs and benefits associated with each alternative. The cost side is the easier part insofar as the various inputs financed by the project have a direct monetary cost (and the indirect cost reflecting the opportunity cost linked to foregone incomes). At the very least, each project should include a table comparing various alternative approaches in terms of unit cost of each intervention and number of beneficiaries.
C. Are the planned investments sustainable? • A key element of the economic analysis is to assess whether the investment planned is sustainable during and beyond the project life. The purpose of the sustainability analysis is to measure the financial implications of the project in order to identify potential financing gaps and avoid financing shortfalls. • Not only look at the financing capacity of public sector. Education investments may also generate private economic benefits that could create a ‘willingness to pay’ among potential beneficiaries. As a result, the analysis should also look at generation of private economic benefits that could create willingness to pay and ability to pay.
D. What are the equity implications? • Another dimension of the economic analysis is to check the consistency of the proposed investment with the Bank’s poverty reduction strategy in the country. What groups would benefit (gender, ethnic, regions, income, etc.)?
II. ECONOMIC ANALYSIS IS POSSIBLE IN EDUCATION Tools of Economic Analysis • Cost-effectiveness (ce) analysis refers to the evaluation of alternatives according to both their costs and their effects with regard to producing some outcome or set of outcomes. • Cost-benefit (cb) analysis refers to the evaluation of alternatives according to a comparison of both their costs and benefits when each is measured in monetary terms.
II. ECONOMIC ANALYSIS IS POSSIBLE IN EDUCATION Tools of Economic Analysis (Cont...) • Cost-utility (cu) analysis refers to the evaluation of alternatives according to a comparison of their costs and the estimated utility or value of their outcomes. • Cost-feasibility (cf) analysis refers to the method of estimating only the costs of an alternative in order to ascertain whether or not it can be considered.

COST-EFFECTIVENESS (CE) ANALYSISCost-effectiveness of Inputs for Portuguese Achievement The least-cost method to produce an additional output. Three steps are required: 1. Regression coefficients from an education production function are used as estimates of the marginal achievement gains attributable to different inputs 2. The total economic costs per student of each individual input are calculated. 3. Alternative inputs are ranked in terms of their contribution to improving scores relative to their costs.
